This time it’s Delray Beach’s upstart Saltwater Brewery that’s getting national attention, as they are collaborating on a black rye IPA with one of the biggest names in craft beer, Terrapin Beer Co. out of Athens, Ga.

Terrapin founder Brian “Spike” Buckowski was at the Saltwater brewery Monday boiling the mash alongside Saltwater’s brewers/co-owners Dustin Jeffers and Bill Taylor as customers in the taproom observed through the wide glass windows.

It’s part of a “beer tour” for Buckowski, who started his trip Saturday in Tampa for Cigar City Brewing’s annual release party of their aged imperial stout beer, Hunahpu. Buckowski plans to brew with two other South Florida breweries on his week-long trip to Florida. He’ll brew a Belgian imperial stout with cherries and raspberries at Miami’s J. Wakefield Brewing Wednesday and Key West’s Bone Island Brewing Saturday between deep water fishing trips.

“This is how you start friendships — over beer,” Buckowski said. “You get to see how others brew, swap war stories. It’s really a learning experience for all of us.”

Their as-yet-unnamed black rye IPA is a combination of the two breweries’ yeasts and half-and-half American and English hops and grains for a nuanced flavor.

They’ve honed the recipe since first discussing it five months ago over oysters in Delray Beach, Buckowski said. It will be served exclusively at the Saltwater Brewery taproom in three-to-four weeks, said Taylor, Saltwater’s brewmaster.

“We wanted to make it really different,” Taylor.

The collaboration Monday was a big draw for Florida’s relatively new craft breweries. Matt Webster, co-owner of Tequesta Brewing Company and Palm Beach Gardens’ new Twisted Trunk Brewing, and Matt Smith, a representative from J. Wakefield, were there to watch the brew and share a few beers.

Terrapin, founded by Buckowski in 2002, made a name for itself when its rye pale ale won a gold medal at the highly respected Great American Beer Festival in Colorado later that year. Since, Terrapin has become a nationwide staple and a model of American craft beer brewing.

Last month Boynton Beach’s Due South Brewing Co.‘s head brewer, Mike Halker, traveled to Barcelona to brew a batch of blood orange and honey IPA with Edge Brewing, an American craft beer brewery that was recently named the world’s best new brewery. They had previously collaborated with Due South on a similar beer — a version of Due South’s Hopicana, using local honey and oranges — that helped put them on the map.
